Proteins Decide Boys Become Boys

Sue Wu submitted, created time 6 months 2 weeks (www.sciam.com)

In research that could give doctors a way to reassign sex in cases of unclear gender, scientists report this week that they have figured out why some children with genes that should make them boys are instead born as girls.

Genetic Link to Schizophrenia Discovered

Sue Wu submitted, created time 7 months 3 weeks (sciencenow.sciencemag.org)

Researchers have found that people with schizophrenia are far more likely than other people to have a certain type of error in their genes. Scientists believe the finding will help them develop new treatments for schizophrenia and identify young people at high risk of developing the disorder.

Team Uncovers New Evidence of Recent Human Evolution

By identifying 582 genes that have evolved differently in different populations in the past 60,000 years, including a dozen that protect people from obesity, diabetes, hypertension, and other diseases, researchers have found powerful new evidence of recent human evolution.

"Normal" genes key to cancer growth

jane2007 submitted, created time 9 months 3 weeks (www.nature.com)

Geneticists have identified genes that are normally present and that seem to be key to the growth and survival of specific cancers. The finding, from a functional-genomics screen of human cells, could offer new drug targets for blitzing tumors.

Human Evolution Is Speeding Up

Eric wu submitted, created time 11 months 1 week (sciencenow.sciencemag.org)

Plentiful food has made it easier than ever before to survive and reproduce in many parts of the world, so it's tempting to think that our species has stopped evolving. But a controversial new study says that isn't so. Far from slowing down, human evolution has sped up in the past 40,000 years and has become 100 times faster in the past 5000 years alone, according to the analysis. This means that even though some people have been globe-trotters who interbreed, most humans on different continents are becoming more different, rather than blending together into one genetically homogenous race.

Inference of transcriptional regulation using gene expression data from the bovine and human genomes

abc01 submitted, created time 1 year 3 months (www.biomedcentral.com)

"Using promoter sequences from human genes is a useful approach when studying gene expression in species with limited or non-existing genomic sequence. As the bovine genome becomes better annotated it can in turn serve as the reference genome for other agriculturally important ruminants, such as sheep, goat and deer."
